At least an 8GB flash drive is required if you want to back up Windows 10. And if you need to create a full backup of Windows 10, a 16GB USB stick is necessary. You need to make sure that the flash drive capacity is larger than your Windows 10.

The commonly used USB flash drives include 8GB, 16GB, 32GB, and 64GB, and there are also some larger-capacity mobile hard drives that have 1TB or 2TB capacity. As a reference, an 8GB of USB flash drive can store 5,120 photos, 1,920 MP2 audio files, and 150,000 pages of documents. So, a 16GB flash drive is enough for a full Windows 10 system backup.

Creating a Windows 10 backup to a flash drive is portable and easy to use, making it convenient to restore Windows 10 system and data on any device when you don't have your computer with you. Many users prefer to use a USB thumb stick to save and back up their data and files.
